Inline Ultrafiltration by Metrohm
Ion chromatography is equipped with Inline Ultrafiltration in many branches to save time and money, e.g.:
- Water
- Environmental
- Pharmaceutical
- Food/beverage
- Chemical

How often is optimal?
Customers often ask me about how often the membrane in an Ultrafiltration cell needs to be exchanged. There is no strict limit to the number of injections per membrane filter. This number strongly depends on the level of contamination of the samples.
The optimal point in time can be easily determined using our intelligent software. MagIC Net allows you to automatically integrate a check standard measurement after a certain number of samples. When the membrane filter begins to clog, the check standard data will deviate from its accepted value. MagIC Net automatically evaluates this value, and a warning message will inform you that it is time to check the system and to exchange the membrane.
Add this feature to any MagIC Net method. Define the monitoring period for the desired result.



Ultimate flexibility for your needs
Monitoring the check standard is useful for several analytical methods. In this example, I explained how to use it to automatically control the performance of the Inline Ultrafiltration. Of course, the MagIC Net software has many more options for flexible methods with feedback. Contact your Metrohm representative if you want to learn more.

This is a great information, thanks to you The membrane filtration process is a physical separation method characterized by the ability to separate molecules of different sizes and characteristics. Its driving force is the difference in pressure between the two sides of a special membrane. Membrane filters technology enables you to bring down overall production costs.
Thanks for such an informative post. You have mentioned the amazing fact. your articles are always amazing. keep posting!
